MSAK (Measurement Swiss-Army Knife)
MSAK is a measurement service hosted by M-Lab that implements two different test protocols:
- throughput: A configurable Websocket-based throughput measurement protocol capable of multi-stream tests. Its design is partially based on M-Lab’s single-stream measurement protocol, NDT. Configurable parameters currently include:
- Number of streams
- Congestion control algorithm
- Test duration
- Per-stream byte limit
- latency: A UDP-based latency measurement protocol.
Run an MSAK throughput test
If you are interested in running an MSAK test, please visit our official speedtest.
We also provide a standalone Go client on the Github repository.
Data collected by MSAK
When you run MSAK, the IP address provided by your Internet Service Provider will be collected along with your measurement results. M-Lab conducts the test and publishes all test results to promote Internet research.
Please review M-Lab’s Privacy Policy to understand what data is collected and how data is used before initiating a test.
Raw data in Google Cloud Storage
All of the raw data and log files from the measurement fleet are archived in their original format and publicly available:
- throughput and latency results
- sidecar data, including tcpinfo snapshots and PCAPs
Details on how M-Lab publishes test data in raw form are provided on our Google Cloud Storage documentation page.
MSAK data in BigQuery
To make MSAK data more readily available for research and analysis, M-Lab loads it into BigQuery tables and views, and makes query access available for free by subscription to a Google Group. The MSAK data is available in the following datasets:
- measurement-lab.msak
- measurement-lab.msak_raw
Find out more about how to get access on our BigQuery QuickStart page.
